Answer:
Efficiency requires that one lighthouse is built since the willingness to pay of all the residents together is larger than the cost of providing the lighthouse
Explanation:
Since the lighthouse is a public good, according to the coase theorem, if the combined willingness to pay for the lighthouse of all of the people living on the islands is higher than the cost of the lighthouse, then a lighthouse should be built.
The total willingness to pay is:

The population willingness to pay is higher than the cost of building one lighthouse ($2000) but lower than the cost of building two lighthouses ($4000). Therefore, efficiency requires that one lighthouse is built since the willingness to pay of all the residents together is larger than the cost of providing the lighthouse.

$86
Explanation:
Missing word <em>"What could be the net annual cost"</em>

Net annual cost = $86
So, the net annual cost of this account is $86.
